Casa Batllo (Batllo House), Barcelona (must see)

Casa Batlló – a prominent symbol of Modernism and Catalan Art Nouveau architecture in Barcelona – is widely hailed as Antoni Gaudí's ultimate masterpiece. Originally constructed in the 1870s, Gaudí undertook a remarkable renovation project in 1904 that transformed this ordinary mansion into a true work of art. Lovingly referred to by locals as the "house of bones" due to its bone-like balconies, or the "house of the dragon" for its roof resembling the humped and glossy scales of a dragon's back, it stands as one of Europe's most peculiar residential buildings.

Few structures in the world possess such an organic quality, where Casa Batlló exudes a sense of being alive rather than inanimate. Any time – day or night, a small crowd gathers outside, gazing up at the undulating facade adorned with a mosaic of fragmented colored glass and ceramic discs. Gaudí's use of light and color is wonderful, particularly in the ceramics, and the curves soften the hard materials quite brilliantly. While exploring the building's interior requires an admission fee that may be considered steep compared to other attractions in Barcelona, it is a worthwhile experience to witness the swirly and curvaceous design.

To fully appreciate Casa Batlló, it is recommended to avail oneself of the free audio guide, which provides valuable insights into the building's historical and artistic context. Although the rooms are now devoid of furniture, the audio guide allows visitors to envision the original furnishings and lighting that once graced the space. As in the case of Casa Milà, Gaudí designed every single bit and piece here, even down to the door handles, ensuring their seamless integration and harmony with the overall form and function.

Despite the presence of an elevator, you are encouraged to walk up the stairs to the rooftop, so as to soak up the atmosphere with its intricate textures and shapes, including glass walls and tiles. At the rooftop's culmination, you'll be rewarded with a scenic view of the surroundings, as well as the up-close encounter with the roof itself including, of course, the signature twisted and tiled chimney pots looking as if they were brought in from a land far, far away...

Tip:
For a fee, you have the opportunity to have your photo taken on the small balcony at the front of the building (as you descend from the rooftop), receiving both a printed copy and an electronic version for a memorable keepsake.
